REFERENCE TO RELATED APPLICATION

The present application is a continuation of and claims priority to U.S. patent application Ser. No. 16/174,903, filed Oct. 30, 2018 and titled “SYSTEMS AND METHODS FOR PORTABLE MONITORING OF INCENTIVE SPIROMETRY,” which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates generally to systems and methods to monitor incentive spirometry. More particularly, the technology is directed to a portable monitoring device configured to monitor use of an incentive spirometer and providing local feedback.

DESCRIPTION OF THE RELATED ART

Postoperative pulmonary complications, including atelectasis, pneumonia, and respiratory failure, commonly arise in patients following major cardiac, thoracic, and abdominal surgeries. Deep breathing exercises help reduce postoperative pulmonary complications by improving postoperative lung expansion and ventilation. Incentive spirometry, designed to mimic natural yawning or sighing, is routinely prescribed by clinicians as a therapeutic strategy to encourage deep breathing. Incentive spirometry forces the patient to take long, deep breaths, which decreases plural pressure and increases lung expansion and gas exchange. Incentive spirometry is accomplished through use of an incentive spirometer, a device that provides feedback when a patient inhales at a predetermined volume for a minimum of five seconds. Inhalation results in the raising of a piston within the device, and a successful attempt is achieved when the piston raises to a set target volume.

BRIEF SUMMARY OF THE DISCLOSURE

DETAILED DESCRIPTION

Embodiments of the present disclosure are directed to systems and methods for monitoring incentive spirometry through a portable device to facilitate self-administration and patient participation. Incentive spirometry is designed to expand lung capacity by forcing a user to breath sustained deep breaths. Use of an incentive spirometer is often prescribed by medical personnel following surgery to prevent post-operative complications, as well as for many respiratory diseases (e.g., pneumonia). As used herein, the term “incentive spirometry” refers to spirometry performed by an individual using an incentive spirometer.

The effectiveness of incentive spirometry for the prevention of postoperative pulmonary complications, or for hindering the progression of many respiratory diseases, is dependent on thorough provider instruction and sustained patient participation. Providers agree that best results are obtained when the device is used consistently. Insufficient self-administration can prevent the resolution of complications leading to prolonged hospital stays, high readmission rates (that are not reimbursed by insurance or hospital), and increased healthcare costs. Incentive spirometers with visual and auditory markers were introduced recently to encourage patient participation, but have had little effect. Furthermore, as hospital admissions increase, medical personnel have less time to spend with each patient to monitor regular incentive spirometer use. Accordingly, there is a need in the art for a device capable of tracking patient incentive spirometer use and providing feedback that encourages further use. The systems and methods disclosed herein provide a way to meet this need by efficiently tracking user compliance, and by notifying medical personnel of that achievement.

Embodiments of the technology discussed herein provide a mechanism for efficiently tracking user compliance, and notifying medical personnel of that compliance. User compliance may be monitored by a portable monitoring device that tracks the inspired air volume by a user, processes that information by comparing it to a desired air volume inputted by medical personnel, and displays a visual indication of results of the comparison. The term “medical personnel” as used herein includes nurses, doctors, physician assistants, researchers, or other persons monitoring incentive spirometry.

FIG. 1 depicts an example incentive spirometer 100 within the prior art. The technology disclosed herein enables greater functionality for medical professionals and users. As illustrated, incentive spirometer 100 may include, for example, an inhalation tube 102 with a mouthpiece 104, a handle 106, a base 120, an air chamber 108, a piston 110 within the air chamber 108, an adjustable marker 112, an indicator 114 inside a separate chamber 116 to indicate whether the user is inhaling too rapidly, and a base 120.

When a user inspires through the inhalation tube 102 (via the mouthpiece 104 in the illustrated example), the piston 110 within the air chamber 108 rises, indicating a volume of air the inspired. The volume of air inspired, as used herein, is the total volume of air inhaled into (or exhaled from) the lungs during a single breath. The adjustable marker 112 may be positioned to indicate, for example, the volume of air the user should reach/attain through inspiration when using the device. The adjustable marker 112 may also indicate, for example, the maximum volume of air achieved by the user through inspiration. The separate chamber 116 located next to the air chamber 108 identifies to the user whether he or she is inhaling too quickly by moving the indicator 114 housed within the separate chamber 116 upwards or downwards. Markers 118 located on the outside of the separate chamber 116 provide guidance to the user, so that the he or she may inspire at a constant or otherwise desired rate.

FIG. 2A is a block diagram illustrating an example portable monitoring device 200 in accordance with the technology disclosed herein. The portable monitoring device 200 enables medical professionals to ensure patient compliance using the incentive spirometer 100 at the device itself, eliminating the need for the communication of raw data to a networked system for determination. As illustrated, the portable monitoring device 200 in various embodiments may include a first switch 204, a second switch 206, a sensor 208, a processor 210, an display 212, a plurality of LEDs 214, a rechargeable battery 216, charging pins 218, and a charging station 220 to which the portable monitoring device 200 may be connected.

The first switch 204 and second switch 206 may be operatively connected to a processor 210. The first switch 204 and second switch 206 may comprise buttons, toggles, or any other components capable of receiving input (e.g., tactile input) from a user. In various embodiments, the first switch 204 and second switch 206 may be used by medical personnel to input, for example, a desired air volume based on the user. As used herein, the term “desired air volume” (or predicted goal, or goal) means a standardized air volume based on the individual user's sex, weight, height, age, and/or other parameters specific to that individual user (e.g., past surgeries, smoking history, workout history, diabetes, history of cancer, other illnesses, etc.). In various embodiments, the desired air volume may be an air volume between the range of about 250 mL to about 3000 mL. The desired air volume could be represented as a range of volumes (for example, between about 450 mL and 475 mL) or discrete volume with some tolerance for variation in achieving the desire air volume (for example, about 550 mL).

In various embodiments, medical personnel can use the first switch 204 to increment the desired air volume, and the second switch 206 allows a medical personnel to decrement the desired air volume. In embodiments, the first switch 204 and second switch 206 may increment or decrement the desired air volume by a range between about 1 mL to about 1000 mL, or from about 200 mL to about 2000 mL. In various embodiments, the desired air volume may be incremented or decremented by a range between about 250 mL to about 500 mL.

The amount of change caused by incrementing or decrementing may vary between embodiments, depending on the level of precision required. For example, the desired air volume may be incremented by 50 mL at a time in some embodiments, or 1 mL at a time in other embodiments. A person of ordinary skill in the art would know how to vary the amount of increase or decrease based on the needs of a particular implementation, and the examples provided should not be interpreted as limiting the subject matter of this disclosure to any particular amount of variation in the increment or decrement.

The first switch 204 and the second switch 206 may be pressed at the same time in some embodiments to reset the desired air volume. Pressing the first switch 204 and the second switch 206 simultaneously in such situations begins a command function to reset the desired air volume. Pressing the first switch 204 and the second switch 206 simultaneously sends a signal to the processor 210, which is operatively connected to the first switch 204 and second switch 206, to initiate a command whereby the processor 210 sends a signal to the LEDs 214, which are operatively connected to the processor 210. Once the command is received by the LEDs 214, the LEDs 214 will begin blinking and the desired air volume may then be inputted. If the LEDs 214 do not blink, the first switch 204 and second switch 206 may be simultaneously pressed again to resend the command. In embodiments, once the desired air volume is set, the first switch 204 and the second switch 206 may then be pressed and held simultaneously to set the new desired air volume.

In embodiments, the first switch 204 and second switch 206 may be pressed simultaneously to reset the elapsed time. The reset of elapsed time in this manner may occur simultaneously with resetting the desired air volume as discussed above, while other embodiments may have the first time the switches are pressed at the same time reset the desired air volume and a second time the switches are pressed at the same time resets the elapsed time. In other embodiments, a time reset switch (not pictured) may be included to reset the elapsed time.

The switches 204, 206 may be configured to perform a variety of functions of the portable monitoring device 200, some of which are discussed above. In various embodiments, the switches 204, 206 may be configured, individually or in combination, to perform one or more of the following functions: increment/decrement desired air volume; set the minimum desired air volume; set one or more thresholds; control the display 212; initiate a transfer of data from the portable monitoring device 200 to a remote location; among others. In various embodiments, additional switches may also be included in addition to the first switch 204 and second switch 206.

In various embodiments, the actions of switches 204, 206 may vary depending on the function to be performed. For example, in some embodiments one or more switches may be configured to increment a value when pressed, while holding the same switch may activate the configuration of thresholds. Non-limiting examples of the types of actions which the switches 204, 206 may perform include pushing, holding, toggling, twisting, among other depending on the type of switch implemented. In some embodiments, the switches 204, 206 may be different types of switches. For example, in some embodiments first switch 204 may be a toggle, capable of being flipped into one of two positions, while the second switch 206 is a rocker switch capable of being depressed in one or two directions continuously, returning to a neutral position after ever action. As another example, the first switch 204 may be a pushbutton, the second switch 206 a toggle, and a third switch (not pictured) is a rotary or dial. The type of switch may indicate the type of function a switch is capable of performing. A person of ordinary skill in the art would understand the capabilities of different switches and would know what type of switch to implement to perform the various functions of the portable monitoring device 200 discussed above. It should be noted that the use of alternatives to physical switches are contemplated. That is, the functionality one or more of the switches described herein, e.g., switches 204, 206, can be embodied using other mechanisms, for example, such as voice-activated switches/mechanisms that can perform the aforementioned incrementing, decrementing, etc. vis-à-vis audio input.

Although examples of the functions of the first switch 204 and second switch 206 have been discussed with specific reference to each respective switch, a person of ordinary skill in the art would understand that the modifiers “first” and “second” do not connote any priority in positioning on the portable monitoring device 200, or in position relative to each other.

Referring still to FIG. 2A, the portable monitoring device 200 includes one or more sensors 208. The sensors 208 are operatively connected to the processor 210. In various embodiments, the sensors 208 may measure the inspired air volume in the incentive spirometer 100 when the portable monitoring device 200 is connected to the incentive spirometer 100. In various embodiments, the sensors 208 measure inspired air volume by tracking the time of flight of the piston 110 within the air chamber 108 of the incentive spirometer 100, when the portable monitoring device 200 is connected to the incentive spirometer 100. The sensors 208 may track the time of flight through, for example, a light signal, including light signals transmitted from ambient, infrared, laser, or other light emitting sources. The sensors 208 may also track time of flight through, for example, a sound signal. Once the inspired air volume has been received by the sensors 208, the volumetric measurement of air may then be relayed to the processor 210. It is to be appreciated that the sensors 208 may track a plurality of time of flight measurements.

The sensors 208 may further include sensors for detecting a velocity at which air is inputted (i.e. through inhalation/inspiration) into the incentive spirometer 100. In various embodiments, the sensors 208 may include sensors for detecting an acceleration of the piston within the incentive spirometer 100.

The portable monitoring device 200 may also include a processor 210. The processor 210 may include circuits, such as logic or other circuits for one or more of receiving, processing, and/or storing content, data, or other information. The circuits may facilitate the receipt (e.g., as data input) of such content, data, or other information, as well as the generation of such content, data, or other information by the portable monitoring device 200. The circuits may further facilitate the transmission or delivery of such content, data or other information by the portable monitoring device 200. In embodiments, the processor 210 may receive the desired air volume from the first switch 204 and second switch 206, and may also receive detected data form the sensors 208. In various embodiments, the processor 210 receives a plurality of time of flight measurements from the sensors 208. In embodiments, the processor 210 converts the time of flight measurement into an inspired air volume. In embodiments, the processor 210 converts a plurality of time of flight measurements into inspired air volumes. The processor 210 may also receive other types of sensed data, such as the velocity of air input into the incentive spirometer and the period in which air was inputted into the incentive spirometer. The processor 210 can include logic to analyze the data received from the first switch 204, the second switch 206, the sensors 208, and other components of the portable monitoring device 200 to calculate various metrics, including but not limited to: number of attempts; whether a patient succeeded per the parameters; compliance; maximum inspired air volume (i.e., max volume); minimum inspired air volume (i.e., min volume); acceleration of the piston; total time air input was within recommended levels; percentage of time spent within the acceptable ranges for a success; among others. As described herein, an “attempt” is registered when the piston 110 reaches a certain threshold in the air chamber 108. For example, the threshold may be entered as 250 mL; if the piston 110 reaches or exceeds 250 mL in the air chamber 108, an attempt is registered. As described herein, “success” is registered when piston 110 in the air chamber 108 reaches (i.e., equals) or exceeds the threshold and desired air volume input by medical personnel. As used herein, “compliance” is the summation of successes over a period of time (t).

As described herein, the terms “maximum inspired air volume,” or “max volume,” refer to a volume of air associated with the highest point that piston 108 reaches. In various embodiments, max volume may be tracked over a period of time. For example, the highest point that piston 108 reaches over a period of, for example, 5 minutes, is the max volume. As described herein, the terms “minimum inspired air volume,” or “min volume,” refer to the volume of air associated with the lowest point that piston 108 reaches. In various embodiments, min volume may be tracked over a period of time. In various embodiments, the processor 210 may present a visual output of the processed inspired air volume(s), as well as other processed information (e.g., the desired air volume) through the LEDs 214 and/or display 212.

Portable monitoring device 200 may further include a memory 224 for storing thresholds, desired air volumes, inspired air volumes, and various different measurements. In various embodiments, the memory 224 may be a fixed or removable storage medium, such as, for example, a hard disk drive, a solid state drive, a magnetic tape drive, an optical disk drive, a compact disc (CD) or digital video disc (DVD) drive, flash memory, USB memory, or other form of fixed or removable storage medium. The type of storage medium may be dictated on the particular implementation, based on performance and/or form factor requirements that a person of ordinary skill in the art would understand and know how to select the storage medium that is appropriate. In various embodiments, the memory 224 may be computer-readable medium having stored therein computer software or data for performing the various functions of the portable monitoring device 200.

In embodiments, the portable monitoring device 200 such as the one depicted in FIG. 2A may include a display 212. Non-limiting examples of display 212 include: a liquid-crystal display (LCD); an organic LCD (OLCD); a light emitting diode display (LED); an organic light emitting diode display (OLED); digital light processing display (DLP); among others. The display 212 is operatively connected to the processor 210, and receives a information from the processor 210 that may be displayed to the user. Such information may include one or more of the following: desired air volume(s), inspired air volume(s) (e.g., attempts, successes, compliance, maximum inspired air volume, and minimum inspired air volume); time elapsed (in units of hours, minutes, seconds, etc.); or other information that may be useful to the user or medical personnel (e.g., flow rate).

In various embodiments, a user or medical personnel may interact with the display 212 screen. By way of example, such an display 212 may be a touchscreen that accepts various hand gestures as inputs.

As further depicted in FIG. 2A, embodiments of the portable monitoring device 200 may include a plurality of LEDs 214 (i.e., light emitting diode). The LEDs 214 are operatively connected to the processor 210, and receive information from the processor 210 that may be displayed to the user and medical personnel. The LEDs 214 may be any one or more of the following colors: red, green, blue, yellow, purple, white, black, and brown, or any combination thereof of RGB. Let it be appreciated that the list is not meant to be exhaustive, and more colors than the ones mentioned may be used. In various embodiments, the LEDs 214 are colored differently, where a color signifies certain information to the user and medical personnel. For example, in embodiments, the portable monitoring device may include two differently colored LEDs 214. One of the LEDs 214 may be, for example, a red LED and may signify to the user and medical personnel that the desired air volume input has not been achieved, while the other LED may be, for example, a green LED and may signify to the user and medical personnel that the desired air volume has been met. In embodiments, different combinations of colors may be used to signify different achievements.

In various embodiments, the LEDs 214 may be configured to indicate whether a patient has continued to comply with a recommended use over time. For example, an LED 214 may remain green during the period where the patient has been using the incentive spirometer 100 as required, but turn another color if the patient fails to use the incentive spirometer as many times as necessary. In this way, medical personnel can see whether a patient is using the incentive spirometer as scheduled, regardless of whether the patient has achieved the desired levels of performance.

The information represented by LEDs 214 discussed above could also be displayed on the display 212 in various embodiments.

Embodiments of the portable monitoring device may also include a rechargeable battery 216. The rechargeable battery 216 is operatively connected by circuitry to one or more components of the portable monitoring device 200 for supplying electric power. In embodiments, the rechargeable battery 216 is recharged when operatively connected to the charging station 220. Charging pins 218 located on one face of the portable monitoring device 202 interact with the charging station 220 to receive the electrical current. The rechargeable battery 216 may be consisted of any one of the following types: nickel cadmium, nickel-metal hybrid, lead acid, lithium ion, or lithium polymer.

The portable monitoring device 200 or components/features thereof may be implemented in combination with, or as an alternative to, other devices/features/components described herein, such as those described with reference to other embodiments and figures. The portable monitoring device 200 may additionally be utilized in any of the methods for making and/or using such devices/components/features described herein. The portable monitoring device 200 may also be used in various applications and/or permutations, which may or may not be noted in the illustrative embodiments described herein.

As illustrated in FIG. 2B, the portable monitoring device 200 may be operationally attached to the base 120 of an incentive spirometer 100. The portable monitoring device 200 has a top end, and a bottom end, and has a face capable a displaying through a visual indication, a plurality of user information. In embodiments, one face of the portable monitoring device 200 has charging pins 218 for charging the device. In other embodiments, one or more charging ports (not pictured) may be included to charge the portable monitoring device 200.

As illustrated, portable monitoring device 200 may include connecters 230 that are configured to mate with the base 120 of the incentive spirometer 100. The top of the portable monitoring device 200 may be cylindrical in shape, or may be round, square, rectangular, or a combination thereof. The connectors 230 may be mechanical and may include, for example, screws, latches, Velcro, locks, snaps, buttons, magnets, or some combination thereof. In various embodiments, the connectors 230 may be adjustable components, allowing the portable monitoring device 200 to mate with various different incentive spirometers that may have different shaped bases. The connectors 230 may comprise any suitable component for connecting to a generic incentive spirometer. For example, in some embodiments the connectors 230 may be elbow-like latches comprising an arm configured to clamp onto the base 120 and apply pressure in a downward direction to secure the base 120 to the top of the portable monitoring device 200. As another example, the connectors 230 may comprise component pairs configured to secure the base 120 of the incentive spirometer 100 to the top of the portable monitoring device 200, such as a strap and locking mechanism. A person of ordinary skill in the art would understand that a variety of different mechanisms may be used as connectors 230 and that the examples above are not meant to be limiting.

By utilizing a portable monitoring device 200 in accordance with the technology disclosed herein, medical personnel are capable of obtaining results indicative of a patient's progress at the incentive spirometer, without the need to transfer the data to another location. Moreover, medical personnel have greater flexibility in administering therapy through greater control over setting parameters and ensuring patient participation. The ability of connectors 230 to mate with a variety of different bases provides medical personnel with a single tool that can be attached to augment any type of incentive spirometer on hand. This lowers cost by facilitating the collection of relevant data for medical personnel regardless of the incentive spirometer used by the patient.

Further, unlike current approaches to monitoring incentive spirometry, the technology disclosed herein is less complex, allowing medical personnel to more reliably and efficiently ensure compliance by patients with recommended therapy. Current approaches require connection to a laptop or other computer system, complex setups and equipment, and require patients to come to the office. The embodiments of the technology of this disclosure are capable of conducting the required analysis locally at the incentive spirometer without the need for separate equipment, resulting in a less complex system that is smaller and more portable. This makes it easier for medical personnel and patients to view the incentive spirometer data at the device, eliminating the need to utilize other equipment. In some embodiments, the portable monitoring device may include a built in USB connector, enabling the portable monitoring device to be directly attached to a computer after use to store or review data, or (as discussed above) to charge the portable monitoring device.

Moreover, the technology of the present disclosure can be taken home by the patient, facilitating better compliance by eliminating the need to go somewhere else to perform the spirometry. Embodiments of the technology may store monitoring data performed at the patient's home or other non-medical personnel environment, which can then be reviewed by the medical personnel at the next meeting. The patient has the capability to reset, reconfigure, and setup the portable monitoring device at home himself or herself, enabling multiple measurements to be taken and maintained together for review later.

Embodiments of the technology disclosed herein further reduce the need for extensive sterilization techniques. Prior art monitoring solutions allowing for capturing and storing information associated with spirometry require time consuming and/or intensive cleaning and sterilization techniques to enable reuse between patients. Sterilization is required because these prior art solutions are more integrated with the incentive spirometer. Monitoring devices in accordance with the technology disclosed herein, however, reduce the need for such sterilization. The embodiments disclosed are compatible with cheaper, one-patient use incentive spirometers (that are not intended for reuse with another patient and, therefore, no need to sterilize). In this way, the monitoring device can be used in a fast and efficient manner with multiple patients without the need for extensive sterilization techniques. For example, after use with one patient, a monitoring device in accordance with the present disclosure can be removed from the first incentive spirometer, cleaned with a disinfectant wipe, and coupled to a second incentive spirometer for a second patient.

FIG. 3 is a flow diagram illustrating an example method in accordance with the technology disclosed. At a high level, method 300 may be performed to monitor incentive spirometry. The operations of the various methods described herein are not necessarily limited to the order described or shown in the figures, and one of skill in the art will appreciate, upon studying the present disclosure, variations of the order of the operations described herein that are within the spirit and scope of the disclosure. Let it be appreciated that operations of method 300 may be performed multiple times.

The operations and sub-operations of method 300 may be carried out, in some cases, by and/or using one or more of the components, elements, devices, and sub-components of portable monitoring device 200 and/or incentive spirometer 100 (including components thereof as described above), as described with respect to at least FIGS. 1, 2A, 2B, and 3-5 , as well as components, elements, devices, and sub-components, depicted therein and/or described with respect thereto.

In such instances, the description of method 300 may or may not refer to a corresponding component and/or element, but regardless of whether an explicit reference is made, one of skill in the art will recognize, upon studying the present disclosure, when the corresponding component and/or element may be used. Further, it will be appreciated that such references do not necessarily limit the described methods to the particular component and/or element referred to. Thus, it will be appreciated by one of skill in the art that aspects and features described above in connection with (sub-) components, elements, devices, and components, including variations thereof, may be applied to the various operations described in connection with method 300 without departing from the scope of the present disclosure.

Referring now to FIG. 3 , aspects of the example method 300 for monitoring incentive spirometry are depicted. The portable monitoring device is connected to the incentive spirometer at operation 302. At operation 304, medical personnel may set the desired air volume for a patient. The desired air volume may be set as discussed above with respect to FIGS. 1, 2A, and 2B. The desired air volume may correspond to the predicted goal of the user, and may represent a standardized air volume based on a user's sex, weight, height, age, and/or other parameters specific to an individual, including for example, BMI (i.e., body-mass index), exercise history, smoking history, history of cancer, etc. The desired air volume may be an air volume between the range of about 250 mL to about 3000 mL. A person of ordinary skill in the art would know that the desired air volume may vary within the range based on the specifics of the therapy and the capacity of the incentive spirometer.

In various embodiments, the desired air volume is received from the incrementing of, by example, the first switch 204 and/or the decrementing of the second switch 206 discussed with respect to FIG. 2B. For example, the first switch 204 may increment the desired air volume as follows: V _(ref) =V _(ref) +n(500 mL),

where V_(ref) is the desired volume amount and n is the number of times the first switch 204 is pressed. In the above example equation, the increments are set at 500 mL. This increment is merely for discussion purposes and embodiments of the technology disclosed herein can have increments of various size, depending on the level of specificity desired. The inverse may be used for the second switch 206, where the desired air volume is set as: V _(ref) =V _(ref) −n(500 mL).

Although discussed with respect to first switch 204 and second switch 206, this was merely an example of how the desired air volume may be received. In various embodiments, the desired air volume may be received through a different action of one or more switches of the device, as discussed above with respect to FIG. 2A. A person of ordinary skill would not view this recitation of setting the desired air volume as limiting.

In various embodiments, a display of the portable monitoring device (such as display 212 of FIG. 2A, for example) may show the desired air volume to the medical personnel to ensure that it is set correctly. In some embodiments, LEDs or other indicators may be included in the portable monitoring device to indicate whether a desired air volume has been set. For example, a green LED may indicate that the desired air volume is set, while a red or yellow LED may indicate that the desired air volume has not been set yet.

At operation 306, the inspired air volume of the user is captured. A user inhales through the mouthpiece of the incentive spirometer as during regular incentive spirometry. In various embodiments, the inspired air volume may be captured by one or more sensors of the portable monitoring device. The one or more sensors may be configured to determine the inspired air volume through various means, including time of flight of the piston within the air chamber as discussed above. In various embodiments, the inspired air volume may be detected through the use of a light signal, a sound signal, or a combination of both.

At operation 308, the portable monitoring device stores the captured volume of inspired air in a memory or storage component of the portable monitoring device, like the memory 224 of the portable monitoring device 200 discussed with respect to FIG. 2A.

At operation 310, method 300 the portable monitoring device analyzes and processes the data obtained by the one or more sensors. In various embodiments, processing an inspired air volume may include measuring an attempt. An attempt may be registered when the piston 110 reaches (i.e., equals) or exceeds an attempt threshold. An attempt threshold could be a specified air volume that may be between about 0 mL to about 1500 mL. For example, if the attempt threshold is 300 mL; an attempt is registered if the piston reaches or exceeds 300 mL. A person of ordinary skill in the art would know that the specified air volume of the threshold may vary within the range based on the specifics of the therapy and the capacity of the incentive spirometer

In embodiments, processing an inspired air volume may include measuring success. A successful attempt may be registered when piston 110 reaches or exceeds the attempt threshold and reaches/exceeds the desired air volume. For example, an attempt threshold may be 250 mL and a desired air volume may be 1500 mL. In this example, a successful attempt will be registered if the piston reaches/exceeds 1500 mL (meaning that the piston had already passed the attempt threshold of 250 mL, registering this as an attempt). It is to be appreciated that more than one attempt may be measured during a session, with a prior attempt being finished when the piston returns to 0 mL and the next attempt beginning when the attempt threshold is reached or exceeded again. In various embodiments, more than one attempt and/or success may be measured over a period of time. In various embodiments, the portable monitoring device may also record failed attempts, failed attempts occurring when the piston reaches or exceeds the attempt threshold but fails to reach the desired inspired air volume.

In various embodiments, processing an inspired air volume at operation 310 may include measuring compliance. In embodiments, compliance is measured by summating the number of successful attempts over a period of time. For example, the number of successful attempts may be 7 and the time elapsed may be 2 hrs; in this example, compliance will be

$\frac{7*V_{ref}}{2},$ where V_(ref) is the desired air volume and compliance is measured in mL/hr.

In some embodiments, processing an inspired air volume at operation 310 may include registering a maximum inspired air volume. A maximum inspired air volume (i.e., max volume) refers to highest air volume reached over a period of time. In various embodiments, processing an inspired air volume may include registering a minimum inspired air volume. A minimum inspired air volume (i.e., min volume) refers to the lowest volume reached during a valid attempt (i.e., where the piston has reached or exceeded the attempt threshold) over a period time.

In various embodiments, more than one attempt may be measured over a period of time (t). In embodiments, the period of time (t) may be in units of years, months, weeks, days, hours, minutes, seconds, or any combination thereof.

In some embodiments, processing at operation 310 may include measuring success of an attempted inspiration (an inspired air volume during a period of time). Success (i.e., successful inspiration) may be registered when piston 110 reaches or exceeds the certain threshold and reaches/exceeds the desired air volume. For example, a certain threshold may be 300 mL and a desired air volume may be 1400 mL; a success will be registered if the piston reaches/exceeds 1400 mL. It is to be appreciated that more than one successes may be measured. In various embodiments, more than one success may be measured over a period of time (t). In embodiments, the period of time (t) may be in units of years, months, weeks, days, hours, minutes, seconds, or any combination thereof.

A counter may be incremented when a success is registered during a period of time (t) at operation 310. In various embodiments, the period of time (t) may be in units of years, months, weeks, days, hours, minutes, seconds, or any combination thereof. In some embodiments, operation 310 may include summing the plurality of increments over the period of time (t).

In some embodiments, the following algorithm may be employed: V _(acc) =ΣV _(i) _(c) ,c∈[0−p],

where V_(acc) is the accumulated inspired air volume, V_(i) _(c) is the volume of inspired air following each successful attempt c. A time period (t) may have as many as p successful attempts. Thus, each V_(i) represents the desired air volume set by the user (V_(ref)) at a given instant c for discrete events. The accumulated inspired air volume can then be compared with the desired air volume V_(ref) to determine whether a patient as achieved a desire air volume over time, or complied with the recommended therapy.

In various embodiments, the portable monitoring device can measure the inhale/respiratory rate of a patient. The inhale/respiratory rate measured how fast it takes for a single attempt (starting from when the piston reaches the attempt threshold) to reach the desired air volume. For example, the inhale/respiratory rate may be calculated as:

${{RR} = \frac{\left( {V_{ref} - V_{thresold}} \right)}{t}},$

where RR is the respiratory rate and V_(threshold) if the attempt threshold. The calculated RR can be used to calculate an average respiratory rate (RR_(avg)) for the patient over a number of successful attempts, for example

${RR}_{avg} = {\frac{\sum{RR}}{\Delta t}.}$

At operation 312, the portable monitoring device can display the results of the processing operation. In some embodiments, the results displayed could include, but is not limited to: attempt(s); success(es); compliance; maximum inspired air volume; and minimum inspired air volume; or a combination thereof.

In various embodiments, operation 312 may include displaying an elapsed time. In embodiments, the elapsed time may be in units of years, months, weeks, days, hours, minutes, or seconds. In embodiments, the elapsed time may be displayed by the display 212. In embodiments, the elapsed time may be displayed by the plurality of LEDs 214.

In various embodiments, operation 312 may include displaying a desired air volume. In embodiments, the desired air volume may be displayed by the display 212. In embodiments, the desired air volume may be displayed by the plurality of LEDs 214.
